On December 16, 2016, I had shoot test Blackmagic Ursa mini 4.6K uncompress RAW at project timebase 50p.I shot with available light only. I had only 2 Toking Zooms 16-28 and 50-135 T3.0 PL. Shooting at 4.6K 50p RAW consumed huge data rate. I used DaVinci Resolve Studio 12.5.4 to make proxies; ProRes 422 FHD 50p.
I edited proxies in Premiere CC2017 and exported as h.264 for web.
This was ungraded footage. The Uncompress RAW I will upload very soon for anyone to try.
